nceted to the eccentric bearings of the cylinders, and moves with saidbearings, and consists of the following parts: The pair of eccentricbearingstl have fastened to them on the inside of the frame, a pair ofeyes 23 which serve to hold the boxes laterally in the frame. liastenedto these eyes are pins 24 in which are pivot-ally mounted connections25, the other end of which is pivoted on pins 2li which are fastened toarms 27 which are formed on hubs 28 which are fastened to the rockshaft29. Likewise the eyes 30, pins 3l, connections 32, pins 33, arms hubs235 and rockshaft 3G serve a similar function to the second cylinder. It

can be seen that when the shafts 29 and 36V are rocked in one or theother direction, they will move their respective cylinders into or outvof printing relation with the form cylinder. The hub has formed upon ita pair of forked arms .5T andS in which are mounted pins t) and 40; andthe hub 535 has formed upon it a pair of forked arms 4l and l'l2 inwhich are mounted pins and 44.

'ihe manner in which the cylinder-moving nit-,aus is actuated so as totrip the cylinders during the time the cylinder' gaps are passing eachother is as follows; ltcan be seen by referring to thc impressioncylinder that it is se proportioned that the impression surfaces occupyeach about three-eighths of the circmnference of the cylinder, and thegaps between them occupy a little more than oneeighth of thecircumference. Now, by 2uranging au actuating niechanism'wh'ich willperform a movement to trip the cylinders during ene-eighth of therevolution of the impression cylinder, it will accomplish the trippingoperation while the gaps are passing each other: and if when thecylinders are tripged and this movement is utilized for the purpose ofrestoring the impression at, the same portion of the rotation of thecylinder', it will throw the cylinders into impression whilc the gapsare passing one ancther. rl`he njechanism for accomplishing thispreferably includes actuating members which are caused to make aplurality of complete reciproeations (in this case four) to cachrotation of the impression cylinder, or to each cycle of operations ofthe machine; a forward movement only of' a. reciprocation whica takesplace inv one-eighth of one revolution of the impression cylinder) isutilized for the purpose of moving the cylinders into impressionposition when it is tripped, and for tripping the cylinder when Meansare connected to the actuating members to properly time their operationupon the cylinder-moving means to more the form cylinlrs in propersequence `while the gaps are passing each other.

'While the actuating members may be moved in Various Ways, it is donepreferably in the following manner: The pinion 13 has meshing with it agear which is Onequarter the diameter of cylinderl gear l2 and makesfour revolutions to one of the impression cylinder. This gear 45 ismounted on stud 46 fastened in the side frame of the machine,` andformed on this gear is an eccentric 47; said eccentric engagingactuating arm 4S and causing it to make four complete oscillations toeach revolution of the impression cylinder, or a forward oscillation inone-eighth of a revolution of the impression cylinder.

Referring to F ig. l, the position of the parts show the cylinders intripped position; the impression surface 5 and form surface 17 have justpassed the printing point, and the actuating fork 48 has just aboutcompleted one of its return or idle strokes. In a manner hereinafter tobe described, the actuating fork 4S ill new be raised, vcausing theprojection SS) to engage the pin 40, and the continued movement of theeccentric will now cause the actuating fork to make its forward stroke,moving the parts to the yposition shown in Fig. 2, in which case theform cylinder has been moved into printing relation with the impressioncylinder, and the front edge of the impression surface 4 has justreached the printing point and the impression will now he taken upon thesheet of paper which is held by the gripper-s (i. As long as theactuating fork 4S it held in this upper position as shown in Fig. 2 itwill osciilateidly back and forth Without operating to more thecylinder, and the form cylinder will be maintained in printing relationwith the impression cylinder.

l` he setting and timing means for controlling the movement of theactuating fork 48' so that it becomes operative at the properreciprocation is manually operated and includes a guard whereby theoperation is controlled so as to time the positioning of the actuatingfork so that it will be operative only at the time the cylinder gaps arepassing one another.

Fastened in the actuating fork 48 is a pin Il!) which passes through theeye of a connection .30; .Laid connection passing through a swivel alwhich is fastened on a segment gear 52 said segment gear being mountedon a stud 53 which is fastened in the rear side frame 2 of the machine;said segment gear 52 meshes with another segment which is fastened to ashaft 55, said shaft being mounted in the front and rear frames of themachine. Just inside the front frame a lever V i V et. is fastened onthis shaft to the other 'end of which is pivotcd a connection 5T whichhas a slotted holcS through which passes a pin 5i). rlhis pin .59 isfastened in a lever GO inside the front frame` and is connectcdto ashort shaft G1 which passes through the front frame and on the outer endis foot treadie vWhen this foot er p1 essei, he segment, ,Y

drugs upon die movahle hearings 'for with the impression cylinder: Thusit can he seen that when the impression surface misses its impressionfrom thc irst cylinder,` it wiil. always he placed ont of impressionrelation with the second cylinder; and when an iinpression surface isthrown into contact with the first cylinder, it will always receive animpression Jrom the second form cylinder.

li-hile the prinriples einhodied in this invention are shown inconnection .with i multi-color press in which the forni cylindersl areactuated to more when the press is tripped, certain 'features oi' thisin 7-ention canE he applied to di'l'erent types of rotary printingmachines, and may he applied to a machine wherein a single printinglcouple is used and in which the impression cylinder instead o'lz the'forni cylinder is moved when the press is tripped: and it is understoodthat such use is contemplated.

it is also obvious that many features of my invention i'iil oe nsel'fnl'for many pnl poses other than the tripping; of cylinders in printingmachines, and that they magy he appiied in any machine where it isdesirahle to more a part Vfrom one position to another and harsh again,at the will of he operator and in timed relation to the reniaininje;meehanism of the machine.
